Test the Path from Your Computer to a Remote Device
After verifying that the LAN path works correctly, test the path from your computer to a remote
device.
1. From the Windows toolbar, click the Start button and select Run.
2. In the Windows Run window, type
ping -n 10 <IP address>
where <IP address> is the IP address of a remote device such as your ISP DNS server.
If the path is functioning correctly, messages display that are similar to those shown in the
Test the LAN Path to Your Router on page 179.
If you do not receive replies, check the following:
• Check that the IP address of your router is listed in your computer as the default gateway.
If DHCP assigns the IP configuration of your computers, this information is not visible in
your computer Network Control Panel. Verify that the IP address of the router is listed as
the default gateway.
• Check to see that the network address of your computer (the portion of the IP address
specified by the subnet mask) is different from the network address of the remote device.
• Check that your cable or DSL modem is connected and functioning.
• If your ISP assigned a host name to your computer, enter that host name as the account
name in the Internet Setup screen.
• Your ISP might be rejecting the Ethernet MAC addresses of all but one of your
computers.
Many broadband ISPs restrict access by allowing traffic only from the MAC address of
your broadband modem. Some ISPs additionally restrict access to the MAC address of a
single computer connected to that modem. If your ISP does this, configure your router to
“clone” or “spoof” the MAC address from the authorized computer.
